Floating IP rules installed with wrong actions

I have a setup with 3 OpenStack controllers, 1 Karaf and 2 compute nodes.
I have constructed the following topology:
two private networks(each configured with vxlan) and one external network connected to one router.
each private network has one VM.

Ping between vms work fine.
Ping to floating IP (of either vms) doesn't work.

I have investigated the first floating ip, 10.83.5.112, which is used by a vm on compute 1. In the ovs dump flows of compute 1, I see the following flow:

cookie=0x8000003, duration=6378.900s, table=21, n_packets=66, n_bytes=5868, priority=42,ip,metadata=0x222e0/0xfffffffe,nw_dst=10.83.5.112 actions=write_actions(set_field:0x11245->tun_id,output:5)

port number 5 is a tunnel port and not a "vm" port.

Dump model of config/odl-fib:fibEntries/ shows:
{
"destPrefix": "10.83.5.112/32",
"label": 70213,
"nextHopAddressList": [
"10.83.6.5",
"10.83.6.6"
],
"origin": "s"
},

10.83.6.5 is compute1 IP, 10.83.6.6 is compute2 IP.
